For Hooli! 8-)


£20? I'd want a tuned smoke production device for that, not just the instructions! :lol: :lol:


SFB - shush, Mrs Hooli thinks that'd be funny too. I think we'd have to update the lights as I wouldn't be seen riding one in daylight ;)

"I'll bet there's no mention of using Suzuki TS185 pistons or X7 silencers !"

Probably not!
But (if it is the publication I am thinking of then) it will contain lots of useful advice on tuning the existing parts, re-shaping ports and so on.
And, if I am right, details of how to stuff the crankcases to increase primary compression as well as carb suggestions.

Might well save £20 for the purchaser!

Hooli, i have emailed you two scans of Bantam tuning, they are for the 123cc bike but will give you some idea of what to do to your heap.

Good for well over 60mph - what more could you want?

Not really. 4 stroke motor with similar characteristics but less tuneable (I'm guessing it's a YBR125 lump, so probably similar to my CG). Best I saw was a heavily re-engineering bantam with an ariel leader/arrow engine. Having also seen a gorgeous tuned arrow racer, I think that could be a proper laugh!

I have seen one 250 Ariel twin powered BSA Bantam - at Stafford I think - called the "Bleader."

Makes me wonder why BSA did not do something similar.
The Arrows/ Leaders were always regarded as distinctly "odd" looking at the time, which can't have helped sales.

A little ingenuity would have given them a much more desirable bike when the new Learner 250 limit came in - 1965-ish.

Silly Greenbat !
The 'tuning' I was referring to is obviously the replacement of the awful Amal carb (they wear out inside 1000 miles son't you know !) with a nice reliable Mikuni.
This is a popular modification amongst the off-road community.
I believe the Yamaha engine is just there to provide a suitable mounting point for the carb.
